Hi Paul, i am added a comment property to nodes. i got no errors. even tried the "Comment" also got no errors. here's my script:
private static final String NODELABEL = "label"; private static final String NODETYPE = "type"; private static final String NODECOMMENT = "comment"; private static Node underlyingNode; underlyingNode = graphDb.createNode(); underlyingNode.setProperty( NODELABEL, "Node Label"); underlyingNode.setProperty( NODECOMMENT, "Node Comment" ); underlyingNode.setProperty( NODETYPE, "My Root Node" ); i am newbie to neo4j, so i think someone can help you about what could be the problem.
